    Interaction of 3-ethoxycarbonyl(carboxy)-substituted 5,6,7,8-tetrafluorochromones with N-nucleophiles: synthesis of fluorocoumarins
    摘要:
    Polyfluorobenzopyranopyrazoles (isoxazoles) have been prepared via cyclization of 5-tetrafluorophenyl-4-ethoxycarbonyl(carboxy)pyrazoles (isoxazoles) produced by the reaction of 3-ethoxycarbonyl-2-methyl- and 3-carboxy-substituted 5,6,7,8-tetrafluorochromone with hydrazine(hydroxylamine). It has been found that 3-ethoxycarbonyl-2-methyl-5,6,7,8-tetrafluorochromone forms the corresponding 2-ethylidenamino-substituted 1,3-keto esters with ammonia and benzylamine, from which 3-ethylidenamino-4-oxy-5,6,7,8-tetrafluorocoumarins were readily obtained. In contrast to the non-fluorinated analogues, 3-ethoxycarbonyl-2-methyl-5,6,7,8-tetrafluorocoumarins were found to undergo acyl-lactone transformation into coumarin structures under acidic conditions.
